# 多die器件的布局约束
# reference:https://blog.csdn.net/qq_29809781/article/details/99581410
# 布局约束主要使用三条命令：
# create_pblock：创建Pblock
# add_cell_to_pblock：将逻辑单元分配给该Pblock
# resize_pblock：调整Pblock的大小和位置

# 多die器件应用示例：
create_pblock DIE0
create_pblock DIE1
create_pblock DIE2

add_cell_to_pblock [get_pblocks DIE0] [get_cells -quite [list DIE0]]
add_cell_to_pblock [get_pblocks DIE1] [get_cells -quite [list DIE1]]
add_cell_to_pblock [get_pblocks DIE2] [get_cells -quite [list DIE2]]

resize_pblock [get_pblocks DIE0] -add [Xx01Yy01:Xx02Yy02]
resize_pblock [get_pblocks DIE0] -add [Xx11Yy11:Xx12Yy12]
resize_pblock [get_pblocks DIE0] -add [Xx21Yy21:Xx22Yy22]
